Millennial Potash Corp. (TSX.V: MLP) (OTCQB: MLPNF) (FSE: X0D) is making significant strides in advancing its Banio Potash Project in Gabon, West Africa, a development that carries substantial implications for global food security and supply chain resilience. The project, which sits on the Atlantic coast, has attracted backing from both U.S. and Gabonese governments, underscoring its strategic importance.
The U.S. International Development Finance Corporation (DFC) has committed US$3 million in non-dilutive funding to complete a Definitive Feasibility Study, which is now underway alongside an Environmental and Social Impact Assessment. These studies are expected to support the company's mining license application in Gabon. Potash's addition to the U.S. Critical Minerals List in 2025 reflects the commodity's essential role in agriculture and the risks associated with its highly concentrated global supply.
The Banio deposit lies within the West African Evaporite Basin, where drilling has intersected cumulative potash thicknesses commonly exceeding 100 meters. An updated Mineral Resource Estimate from November 2025 reported Measured and Indicated Mineral Resources of 2.45 billion tonnes grading approximately 15.6% KCl, and Inferred Mineral Resources of 3.56 billion tonnes at the same grade. These figures represent increases of 275% and 210% over the maiden estimate, from drilling that covers only about 5% of the company's 1,500 km² license area.
A Preliminary Economic Assessment (PEA) completed in 2024 outlined a solution mining operation producing 800,000 tonnes per year of granular muriate of potash. The PEA reported an after-tax NPV10 of US$1.07 billion, an after-tax IRR of 32.6%, initial capital costs of US$480 million, and operating costs of US$61 per tonne. The cost structure benefits from solution mining, thick potash seams, simple mineralogy, and coastal logistics, with shipping to Brazil—the world's largest potash importer—estimated at approximately US$22 per tonne.
The project's leadership team has a track record of successful exits, having previously led companies such as Millennial Lithium, Potash One, Allana Potash, and Energy Metals, which were acquired for approximately $490 million, $430 million, $170 million, and $1.8 billion, respectively. Management and insiders hold approximately 40% of Millennial's outstanding shares, aligning their interests with shareholders.
Banio has the potential to become Africa's first potash mine, supplying not only Brazil but also the United States, Europe, and Asia. This development is particularly timely given global concerns over food security and the need to diversify sources of critical minerals. The U.S. government's involvement, through the DFC, highlights the geopolitical significance of reducing dependence on dominant potash producers.
As the company progresses with its feasibility studies and environmental assessments, the implications for the global potash market are noteworthy. If successful, the Banio project could offer a new, cost-competitive source of potash, potentially stabilizing prices and ensuring a more secure supply chain for agricultural markets worldwide.
